We will use _ as CLI level divider. The XML definition filename and also
the Python helper should match the CLI node.
Example:
set interfaces ethernet -> interfaces_ethernet.xml.in
set interfaces bond -> interfaces_bond.xml.in
set service dhcp-server -> service_dhcp-server-xml.in

Remove what was not working on 1.3, migrate what was working to new syntax and extend feature for ipv6.

- Moves MSS node out of `tcp-flags.xml.i` and into `tcp-mss.xml.i`
- Update smoketest to verify TCP flag matching

The following commands will enable nftables flowtable offload on interfaces eth0 eth1:
```
set firewall global-options flow-offload software interface <name>
set firewall global-options flow-offload hardware interface <name>
```
Generated nftables rules:
```
table inet vyos_offload {
flowtable VYOS_FLOWTABLE_software {
hook ingress priority filter - 1; devices = { eth0, eth1, eth2, eth3 };
counter
}
chain VYOS_OFFLOAD_software {
type filter hook forward priority filter - 1; policy accept;
ct state { established, related } meta l4proto { tcp, udp } flow add @VYOS_FLOWTABLE_software
}
}
```
Use this option to count packets and bytes for each offloaded flow:
```
set system conntrack flow-accounting
```
To verify a connection is offloaded, run
```
cat /proc/net/nf_conntrack|grep OFFLOAD
```
This PR follows firewalld's implementation: https://github.com/firewalld/firewalld/blob/e748b97787d685d0ca93f58e8d4292e87d3f0da6/src/firewall/core/nftables.py#L590
A good introduction to nftables flowtable: https://thermalcircle.de/doku.php?id=blog:linux:flowtables_1_a_netfilter_nftables_fastpath

Kernel 5.15.y and newer only support an upper boundary of 255.
vyos@vyos:~$ sudo sysctl -w net.netfilter.nf_conntrack_tcp_max_retrans=255
net.netfilter.nf_conntrack_tcp_max_retrans = 255
vyos@vyos:~$ sudo sysctl -w net.netfilter.nf_conntrack_tcp_max_retrans=256

This commit fixes an error introduced by 43fcc0db0 ("conntrack: T3275: migrate
'disable' syntax to 'enable' syntax for the new default behavior") as the
<valueless/> option can only be used on leafNodes. THis triggered the following
build error:
ValueError: <valueless/> is only allowed in <leafNode>

default behavior

Some application layer gateway (ALG) modules can be disabled during runtime
if requireq.
